Birthday Girl Keira Knightley Demonstrates How to Bare Your Legs This Spring Without Freezing to Death

While out and about promoting her flick Anna Karenina, Keira was spotted dressed in head-to-toe Richard Nicoll. (This wasn't the first time Keira supported the English designer—she also wore a sherbet-color dress from the same collection during this tour.) Though Keira was out in sunnier L.A. temps, I thought her look was the perfect way to show some leg in nippier climates (like here in New York) without freezing your butt off. Pairing a jacquard skirt and strappy sandals on the bottom with a two-tone cashmere sweater on top to keep warm, Keira pulled off such an slouchy-but-ladylike vibe. One word: adore.
